JESSE M. FLEMING, OF DRUIVIRIGHT, OKLAHOMA.

SAND TRAP.

Application filed June 7, 1821.

To all whom it may concern:

Be it known that I, Jnssn M. FLEMING, a citizen of the United States,residing at Drumright, in the county of Greek and State of Oklahoma,have invented a new and useful Sand Trap, of which the following is aspecification.

This invention relates to sand traps, employed in connection with oilwell apparatus, the primary object of the invention being to providemeans supported ad acent to the lower end of the pipe to guard thestrainer and inlet openings of the pipe from floating sand entering thesame.

A further object of the invention is to provide a device of thischaracter which may be readily and easily applied to the pipe, and onewhich will not interfere wlth the positioning of the pipe withln thewell.

With the foregoing and other objects 1n view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, may be made within thescope of what is claimed, without departing from the spirit of theinvention.

Referring to the drawing Figure 1 is a side elevational view of a wellpipe showing the sand trap and guards as applied thereto, the sand trapbeing partly broken away to disclose the straining elements thereof.

Figure 2 is a sectional view taken on line 22 of Figure 1.

Figure 3 is a sectional view taken on line 8-3 of Figure 1.

Figure 4 is a fragmental detail view partly in section disclosing thelower end of the pipe and strainer supported thereby.

Referring to the drawing in detail, the reference character 5 designatesthe upper portion of the well pipe or tubing which is secured to thelower section of the pipe or tubing as by means of the collar 6.

The lower portion of the pipe is provided 0 with the usual openings 3which are arranged in vertical spaced relation with each other toprovide communication between the interior of the pipe and the well forthe purpose of admitting oil thereto. At the Serial No. 475,671.

lower end of the pipe 5 is positioned a strainer 7 that substantiallyhouses the lower end of the pipe 5, and is secured to the pipe 5by meansof the wire 7'.

Positioned on the lower extremity of the pipe, at a point adjacent tothe strainer 7 is a flared collar 8 which is of a diameter permittingthe side walls thereof to be held in spaced relation with the side wallsof the pipe.

Disposed in spaced relation with the collar 8 is a cone shaped collar 9which also has the flared portion thereof disposed in spaced relationwith the pipe, so that when the pipe is positioned within a well, thecollars will contact with the walls of the well and support the pipe 5in spaced relation therewith. Surrounding the pipe and enclosing theapertured portion thereof is a covering of burlap or other suitablefabric indicated at 10, and as shown, the burlap is secured to the pipeby means of the covering 11 of wire mesh material. Thus it will be seenthat the openings 3 are guarded to insure the oil enterin the pipe beingfree of sand or other foreign matter.

From the foregoing it will be seen that floating sand above the collar 9will ordinarily be held from the openings 3 by means of the collar 9,while any particular amount of oil and sand which may pass the collar 9will be thoroughly strained before the same enters the pipe 5 andcontacts with the valves thereof. It will be seen that the strainer 7 isalso protected from the floating sand by means of the collar 8, whichguards the strainer, catching the sand at a point above the strainer 7to the end that fluid is taken in through the strainer 7 from the bottomof the well.

Having thus described the invention, what is claimed as new is 1. In adevice of the character described, a pipe having openings formedtherein, a strainer disposed at one end of the pipe, a flared collarsecured to the pipe adjacent to the strainer, a cone-shaped collarsecured to the pipe and disposed in spaced relation with the flaredcollar, and means secured to the pipe between the flared collar andcone-shaped collar for guarding the openings of the pipe.

2. In a device of the character described, a pipe, a strainer disposedat one end of the pipe, means supported by the pipe and dis- Intestimony that I claim the foregoing posed adjacent to the strainer forguarding as my own I have hereto affixed my sig- 10 the strainer andahcofie-shaped ciolllar havci nature in the presence of tWo Witnesses.-
